• Utilize NAV 1 or NAV 2 receivers.

POSITION ERROR [POSN ERROR]

1. GPS signal will flag.

2. Utilize NAV 1 or NAV 2 receivers.

LOSS OF RECEIVER AUTONOMOUS INTEGRITY MONITORING (RAIM)

During enroute, oceanic, terminal, or initial approach phase of flight:

1. Continue to navigate using GPS.

2. Verify position using NAV 1 or NAV 2 every 15 minutes. Or:

3. Utilize NAV 1 or NAV 2 receivers. During Final Approach:

1. GPS navigation will continue for up to 5 minutes. 2. Conduct missed approach.

3. If terminal GPS sensitivity is lost during the missed approach, revert to NAV 1 or NAV 2 receivers.

GARMIN TERRAIN AWARENESS AND WARNING

SYSTEM (TAWS)

(TH-2138, TH-2141 and after and prior airplanes in compli- ance with Service Bulletin. 34-3774.)

TAWS FORWARD LOOKING TERRAIN CAUTIONS

[TERRAIN]

Voice Caution Alert: See the following table.

Reduced Required Terrain (or Obstacle) Clearance (RTC or ROC) Caution - Voice caution alerts and annunciators are pro- vided if the airplane flight path is projected to violate a set of terrain and obstacle minimum clearance requirements within approximately 60 seconds.

Imminent Terrain (or Obstacle) Impact (ITI or IOI) Caution - Voice caution alerts and annunciators are provided if the air- plane flight path is projected to impact the terrain or an obsta- cle within approximately 60 seconds.

In all cases, a yellow [TERRAIN] will be displayed on the PFD and the MFD TAWS page, if selected. One of the following voice caution alerts will be heard.

REASON VOICE CAUTION ALERT

Violation of Required Terrain Clearance (RTC) Requirements within 60 seconds

“Caution Terrain, Caution Terrain”

Imminent Terrain Impact (ITI) within 60 seconds

“Terrain Ahead, Terrain Ahead” Violation of Required Obstacle

Clearance (ROC) Requirements within 60 seconds

“Caution Obstacle, Caution Obstacle”

Imminent Obstacle Impact (IOI) within 60 seconds

“Obstacle Ahead, Obstacle Ahead”

NOTE

When the TAWS Page is not displayed and a terrain or obstacle caution is issued, a pop-up window is displayed in the lower right corner of the MFD displaying an appropriate annunciator. See Section 7, SYSTEMS DESCRIPTION.

NOTE

Pilots are authorized to deviate from their current air traffic control (ATC) clearance to the extent necessary to comply with a TAWS caution.

The following procedure should be followed if any of the pre- ceding cautions occur.

1. Stop descending, or climb, and/or turn as necessary, based on analysis of all available instruments and visual observations, in order to cancel the alert. (The voice caution alert will be repeated until the threat no longer exists.)

2. Advise Air Traffic Control as necessary.

EXCESSIVE DESCENT RATE CAUTION [TERRAIN]

Voice Caution Alert: “Sink Rate”

Excessive Descent Rate (EDR) Caution - A Voice caution alert and annunciator are provided if the airplane is below 5,000 feet and approaching the terrain at an excessive rate of descent in relation to the altitude above the terrain. The cautions will be provided whether or not the TAWS system is enabled. A yellow [TERRAIN] will be displayed on the PFD and the MFD TAWS page, if selected, and the voice caution alert “SINK RATE” will be heard. If corrective action is not taken, an EDR warning will follow the caution. See Section 3, EMERGENCY PROCE- DURES.

Abnormal Procedures Model G58 Section 3A

NOTE

When the TAWS Page is not displayed, and an EDR caution is issued, a pop-up window is displayed in the lower right cor- ner of the MFD displaying a yellow [SINK RATE].

The following procedure should be followed if the above cau- tion occurs.

• Level wings and reduce rate of descent until visual and aural alerts cease.

NEGATIVE CLIMB RATE AFTER TAKEOFF [TER- RAIN]

Voice Caution Alert: “Don't Sink”

A Voice caution alert and annunciator are provided to alert the pilot that the airplane is losing altitude after takeoff. The cau- tions will be provided whether or not the TAWS system is enabled. The alerts are only active if all of the following condi- tions are met:

• The takeoff phase of flight. (The system must have detected an actual takeoff. Alerts are not provided for go- arounds or missed approaches.)

• The height above the terrain is less than 700 feet. • The airplane is less than 2 nm from the departure airport. • The airplane heading is less than 110 from the departure

runway heading.

The following procedure should be followed if the above cau- tion occurs.

• Level wings and immediately establish a positive rate of climb.

PREMATURE DESCENT DURING AN APPROACH

[TERRAIN]

Voice Caution Alert: “Too Low, Terrain”

A Voice caution alert and annunciator are provided to alert the pilot that the airplane has descended too low for the particular kind of approach; e.g. a visual approach (no approach loaded), a non-precision approach, or an ILS approach.

The following procedure should be followed if the preceding caution occurs.

• Initiate positive action to fly the airplane up to the glide path to cancel the alerts.

DITCHING, OFF-AIRPORT LANDING, OR FLYING VFR AROUND UNIQUE TERRAIN

Inhibit the visual and voice alerts of the TAWS system using the following procedure. The terrain page will remain opera- tional on the MFD and the GPWS functions will still be opera- tional.

On the MFD:

1. Large FMS Knob. . . .SELECT THE MAP GROUP 2. Small FMS Knob . . . SELECT THE TAWS PAGE 3. Press the MENU Key

4. Small FMS Knob . . . SELECT “INHIB TAWS” 5. Press ENT

ALTIMETER DISAGREEMENT

If a significant difference is noted between the altitude dis- played on the PFD and the standby altimeter, the GPS ALT displayed on the MFD may be used as a third altitude source to help resolve the discrepancy.

April, 2008

Abnormal Procedures Model G58 Section 3A

The GPS ALT displayed on the MFD is a calculated value and must not be consid- ered as a primary source of altitude. The GPS ALT and the altitude displayed on the PFD may differ by 100 feet or more. Its use is not approved for navigation.
